If after checking that the sensor is registered and virtual environment exists,
sensor still doesn’t appear to be running or working, you should run sensor
container service in the foreground in debug and single sensor mode. In this
mode sensor container will only run the sensor you specified and all the log
messages with level DEBUG and higher will be printed directly to the console.

The log output will usually give you a clue as to what is going on. Common issues
include typos and syntax errors in the sensor class code, uncaught exceptions
being thrown that causes the sensor to exit, etc.
